Analytical analysis and simulation of losses for ideal structures are provided. Effect of fabrication nonidealities, such as surface roughness is also considered. In dielectric waveguide, the dielectric losses are the main loss mechanism, and Silicon tan8 is low above 1 THz, but increases rapidly at lower frequencies. The loss in metallic waveguides increases with increasing frequency. For ideal structures, the Silicon dielectric slot waveguide shows lower loss over 1.2 THz than the metallic waveguide. The effect of rough metal surface in the metallic waveguide increases the loss, making the dielectric waveguide interesting at even lower frequencies.","PeriodicalId":441407,"journal":{"name":"2018 11th Global Symposium on Millimeter Waves (GSMM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129722322","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we consider the downlink communication of a mmWave massive MIMO system and propose a novel hybrid beamforming algorithm based on extended block diagonalization (BD) and equal gain transmission (EGT) method with near optimal performance and low complexity. At the RF analog domain, we harvest the large array gain by using the EGT method and discrete Fourier transform (DFT) matrix. At the baseband digital domain, the extended BD algorithm is performed. The extended BD algorithm considers both the interference null space as well as the characteristic of the user's signal space while the traditional BD algorithm only considers the interference null space. Then we also analyze the performance of the proposed algorithm in different channel models. According to the simulation results, we find that the proposed algorithm performs well both in sparse channels and Rayleigh channels. To the best of author's knowledge, the performance of the proposed algorithm is better than other low complexity hybrid beamforming algorithms.","PeriodicalId":441407,"journal":{"name":"2018 11th Global Symposium on Millimeter Waves (GSMM)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114454192","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At millimeter wave frequencies, a large effective aperture can be accommodated in a physically small area to overcome the high channel loss in these spectrum bands. The ability to dynamically steer and shape active antenna beam(s) to track users., overcome changing channel conditions, and focus the radiated energy into the desired direction provides additional degrees of flexibility and enables better performance for 5G radio system designs. To provide an over-the-air interface for previous generations of radio access networks, traditional architectures have relied upon separate, passive antennas connected by radio frequency cables to active radio transceivers. Active antenna systems, also known as phased array antenna systems, are an advancement from these previous radio access architectures. To implement an active antenna, a array of active radiating elements is utilized to combine passive antenna functions with active amplification and signal conditioning capabilities. Active antennas are an enabling technology for millimeter wave 5G communication systems that create a fundamental architecture shift requiring new Figures of Merit (FoMs). The 5G active antenna FoMs defined in this paper provide methods for antenna performance comparisons and wireless system evaluation.","PeriodicalId":441407,"journal":{"name":"2018 11th Global Symposium on Millimeter Waves (GSMM)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128481561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While components for the ultra-high bandwidth Terahertz wireless communications were in rapid development over the past several years, however, their commercial availability is still lacking. Nevertheless, as we demonstrate in this work, due to recent advances in the microwave and infrared photonics hardware, it is now possible to assemble high performance hybrid THz communication systems for real-life applications. We present design and performance evaluation of the photonics-based Terahertz wireless communication system for the transmission of uncompressed 4K video feed that is built using all commercially available system components. The Terahertz carrier frequency is fixed at 138 GHz and the system is characterized by measuring the bit error rate for the pseudo random bit sequences at 5.5 Gbps. By optimizing the link geometry and decision parameters, an error-free (BER<10−10) transmission at a link distance of 1m is achieved. Finally, we detail integration of a professional 4K camera into the THz communication link and demonstrate live streaming of the uncompressed HD and 4K video followed by analysis of the link quality.","PeriodicalId":441407,"journal":{"name":"2018 11th Global Symposium on Millimeter Waves (GSMM)","volume":"107 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128656288","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
